Low-clearance lead screw nuts

What should you do in the event of unwanted axial clearance?

What is axial clearance anyway?

What is the axial clearance?

What options does the igus product range offer in this case?

Low-clearance lead screw nuts

The zero-backlash lead screw nut

  • Lifelong minimal axial backlash
  • More precise positioning and infeed movements
  • In dryspin high helix threads
  • Flange lead screw nut
  • Thread direction: RH
  • Material: iglidur J

The low-clearance lead screw nut

  • Reduced axial clearance due to circumferential radial pretension
  • Very quiet operation due to reduction of possible vibrations
  • Cost-effective alternative to the zero-backlash nut
  • In dryspin high helix and trapezoidal thread up to thread diameter 14mm
  • Flange lead screw nut
  • Thread direction: RH
  • Material: iglidur J
